Spect Nuclear Brain Scan

SOUTHEAST MEDICAL IMAGING

SPECT NUCLEAR BRAIN SCAN Name: AB Date of Service: 10/8/2009 ID: DOB: Referring MD: SCHERER, CHARLES Age: 32 Sex: M Indications: FOLLOW UP BRAIN SCAN 09/10/2009, Technologist: GA 09/24/2009

AB - Error: Reference source not found AB - Error! Reference source not found. HISTORY: History of head trauma TDI which caused bleeding in the left eye and from the left ear, posttraumatic stress disease, headache, dizziness and tinnitus. The patient has now completed 40 hyperbaric oxygen treatments.

COMPARISON: Comparison to previous SPECT brain scan of 09/10/2009 and 09/24/2009.

TECHNIQUE: Following injection of 29.3 mCi of Technetium-99m Ceretec, SPECT imaging of the brain was obtained in axial, sagittal, and coronal planes. Images are presented in black and white and in color. Also 3D images are provided.

FINDINGS: There is still an abnormal pattern of localization in the frontal areas, greater on the left than on the right and a very patchy type of pattern to both cerebral cortexes. There is a moderate amount of normal appearing brain, particularly in the parietal areas and occipital areas. There is now moderate localization in the cerebellar areas, more on the left than the right. The basilar ganglia areas continue to show decreased localization again greater abnormality on the left than the right. There is again suggestion of some increase in the size of the ventricles. Study otherwise appears normal.

Conclusions  Further improvement in the pattern of localization in both cerebral cortexes and particularly improvement in the localization in the cerebellar area is greater on the left than the right. There remains significant abnormality in the frontal regions, again greater on the left than the right. The basilar ganglia areas continue to show abnormal localization though the degree of localization has improved particularly in comparison to the first study of 09/10/2008. All of the areas have shown some improvement but still remain abnormal. All areas of abnormality have peri-ischemic penumbra. The improvement shown on the serial SPECT scans, in comparison particularly to the study of 09/10/2009 shows improvement that would correlate with the patient's clinical symptom improvement with the course of hyperbaric oxygen therapy and rehabilitative procedures but the pattern shown would suggest additional hyperbaric oxygen therapy or other treatment of the brain in the future.
